With one method of a procedure called acceptance sampling, a sample of items is randomly selected without replacement and the entire batch is rejected if there is at least one defective unit. The ABCD Electronics Company has just manufactured 4500 write-rewrite CDs, and 150 are defective. If 4 of these CDs are randomly selected and tested, what is the probability that the entire batch will be rejected? Report the answer as a percent with one decimal place accuracy. (You need not enter the "%" symbol) Probability
It is a case of Binomial distribution because the probability of an event is fixed , there are fixed number of trails and there are two events only, the two events are- the write-rewrite CD is not defective OR the write-rewrite CD is defective
